Description
Technical field
The present invention relates to mechanical equipment technical field, more particularly to a kind of Novel punching machine.
Background technology
Punch press is a kind of equipment for pressing sheet material.Existing punch press includes following three major types：1st, crank type punch press；2、
Toggle joint type punch press；3rd, multi link punch press.
Crank type punch press is easily fabricated, and cost is low, and the inertia of the diel during high speed stamping is big, the depth of punching press
It can change with velocity variations, precision is difficult to control, in addition, the bottom dead centre residence time of crank type punch press, (i.e. mould rigid connection was touched
End point of the point to punching press occurs for the strength of time of the time of workpiece to mould punching to workpiece set depth either punching press
Time) it is short, cause the metal fluidity of workpiece to be machined not good, easily cause stamping surface it is more coarse, pressed through in high-speed punching
Stamping parts is second-rate in journey, and the bent axle of the crank type punch press is big by the reverse impact power of mould, and the abrasion to equipment is big,
Shorten the service life of equipment.
Toggle joint type punch press manufacture difficulty is slightly higher, and cost is also higher, but the inertia that drive mechanism is used is relatively small, precision
Higher, its bottom dead centre residence time improves a lot than crank type punch press so that the stamping surface of workpiece to be machined is relatively smooth, carries
The high stamping quality of stamped workpieces, the bent axle of the toggle joint type punch press is smaller by the reverse impact power of mould, but board by
Reverse impact power to mould is still very big, and the abrasion to equipment is big, shortens the service life of equipment, is carrying out high speed stamping
When, the depth of punching press can still change with velocity variations, and lower dead point position precision is difficult to control.
The manufacture difficulty of multi link punch press is high, and cost is high, inertia very little, its bottom dead centre residence time and crank type punch press phase
Closely, but the press depth of mould is easily controllable during high speed stamping, precision is high so that the stamping surface of workpiece to be machined is more
It is smooth, the stamping quality of stamped workpieces is improved, and the reverse impact power that multi link punch press is subject to is smaller, the abrasion to equipment
It is smaller, extend the service life of equipment.
